Description

Water storage refrigerator hot.

Technical sector

The present invention is related to applications that combine equipment capable of cooling or freezing food and drinks, as well as generate hot water Simultaneously, both domestically and industrially.

Background of the invention

Currently, most homes have with independent systems for both refrigerating food and to heat water. In refrigerators, the compressor consumes electrical energy, part of which is dissipated to the environment in form of heat, which is generally not used and that increases thermal gains of housing, which can increase the air conditioning consumption during the summer months.

Likewise, the systems for heating Water mainly consist of fossil fuel boilers, and even electrical resistors; systems that involve an expense high energy due to losses generated in the installation. Heat pumps are a solution energy efficient for water heating and its use It is increasingly widespread.

However the inventor has no knowledge one of a team like the one that submits that request, which integrates the refrigerator and the water accumulator in a single device hot, thus benefiting from the economic and space savings that entails the unification of both teams, and most importantly, the energy saving of using the same refrigeration unit to cool the refrigerator and heat the water so simultaneous. To all this is added the high performance involved the use of heat pump systems.

In this way, with the same energy consumption, we will have completed two fundamental services of life daily as are the production of ACS and the cooling of food and drinks.

Description of the invention

Specifically, the object of the invention is a apparatus of variable shape and size which integrates inside a water storage tank and a refrigerator cabinet in the We will keep food or drinks to cool.

The team also has a circuit refrigerator composed of a compressor, an expansion element, an evaporator, a condenser, along with the pipes and elements of union between them.

The condenser will be submerged in the inside the accumulator as a heat exchanger, or external form, always in intimate contact with the deposit. He evaporator will be in direct contact with the chamber of refrigeration. The rest of the elements: compressor, element of expansion, etc ... will be located in a compartment for this end.

Therefore, while the equipment is in operation, the refrigeration cycle works in such a way that the compressor sucks the gas from the evaporator, which has changed to state gaseous by absorbing heat from the food chamber. This gas is driven by the compressor towards the condenser, where it is transferred to the water all thermal energy captured in evaporation processes and compression, going back to a liquid state. The element of expansion is responsible for closing the cycle. In this way the heat of the cold store is removed and used to heat the water accumulator

Since the necessary energy demands both to heat water and to cool the chamber not will generally coincide in time, the team foresees a heat exchanger that will work automatically to adjust the needs of both systems. This process will be regulated by means of equipment control.

The final set is heated originating a single block, so the final appearance is of a single device, coated on the outside by an envelope protective

The final aesthetics of the refrigerator with hot water cylinder can be as diverse as designs are want to do the same, always maintaining the requirements indispensable technicians for its operation.

We understand therefore that the improvement with accessory elements or different forms of the object here presents are not elements that come to create this invention another new and different with enough inventive novelty.

It is not considered necessary to make the content of this description for a subject matter expert can understand its scope and the advantages derived from the invention, as well as develop and implement the object of the same.

Description of the drawings

To complete the description that is being performing and in order to help better compression of peculiarities of the refrigerator with hot water cylinder that we propose, it is accompanied by this specification, as integral part of it, of the drawings arranged in the following pages in which, for explanatory purposes and not In any case, the following has been represented:

Figure 1, in which a scheme of the refrigerator with hot water cylinder.

Description of a preferred embodiment

The detailed description of the embodiment preferred of the process of the present invention and of the elements that compose it, it is done in view of figure 1. In Figure 1 shows the refrigerator with water accumulator hot (1) for domestic application, which is composed of the cold room (2) of food and beverages, on which find the hot water cylinder (3) pressurized and Made of a metallic material. The accumulator has a network water inlet (12) located at the bottom and a hot water outlet (13), located in the upper area of the same, which allows to obtain the hottest water in the region, taking advantage of the thermal stratification that takes place in the inside. The set formed by the cold store and the accumulator is covered by thermal insulation (9), and on this set is a compartment (14) that houses the refrigerating equipment The refrigeration equipment consists of the compressor (4), expansion valve (5) and other elements of union (15), electrical and safety necessary for the system function properly The capacitor (6) is located in the inside of the accumulator, and is made of metallic material, presenting form of coil. The high pressure gas comes to him and temperature that is moved by the compressor, yielding to the water in this point the accumulated thermal energy. Once expanded, the coolant reaches the internal evaporator (7) where evaporates by stealing the heat contained in the cold store.

In case the hot water needs are superior to those of refrigeration, the team foresees a second evaporator (8), located outside the equipment, and configured in Metal panel shape with inflated inner circuit, in this preferred embodiment This outside evaporator will be used to capture the heat of the environment and heat the water, when the camera refrigerator is at the preset temperature. Both of them evaporators, interior (7) and exterior (8) are connected in parallel.

The automatic operation of the equipment will go regulated by the control means, which will open the keys cutting (11) that allow the passage of fluid to the evaporator outside, when its use is needed, because energy is demanded in the water storage tank, and instead it is not necessary to remove  energy of the cold store.

In its entirety, the set is covered by a protective envelope (10).
